South Korea’s dependence on China for exports hit a new high last year.

The Ministry of Trade, Industry and Energy said China accounted for 26-point-one percent of South Korea’s exports last year at 559-point-seven billion U.S. dollars.

The percentage of South Korea’s exports bound for China reached 20 percent in 2005 for the first time. It fell slightly in 2011 and 2012 before jumping last year.

Cell phone and automobile parts and semiconductor chips led South Korea’s exports to China. South Korea posted a trade surplus of 60-point-six billion U.S. dollars against China last year, while Korea’s overall trade surplus was 44-point-two billion U.S. dollars.
